Its deja vue all over again, same issues as before.

As before all front end computers powered down with the exception of cdsh8 and psl0. When we powered them back up all recovered except h1sush12, which has again lost its 3rd Adnaco backplane in its IO Chassis, even though this is a new BP installed this morning.

HWS at end have gone down, check. 9th port on timing master (dts) is down, check. FMCS EPICS is down, check.

this time h1cdrfm's adnaco expansion chassis at the end stations have not gone down though.

Looks like the PSL Diode Room Beckhoff has gone down this time.
